OIL-TORCH.

SPECIFICATION forming part of Letters Patent No. 566,024, dated August 18, 1896. Application led October 23, 1894:. Serial No. 526,899. (No model.)

To all whom it may concern:

Beit known that we, LOUIS SoHUrrE, a citizen of the United States, residing in Philadelphia, in the county of Philadelphia, and AXEL S.VOGT,a subjectofthe King ofSWeden and Norway, residing in Altoona, county of Blair, State of Pennsylvania, have invented a new and Improved Oil-Torch, of Which the following is a specification, reference being hadto the accompanying drawings, which form a part thereof.

Our invention relates to oil-torches, and has for its object to provide a portable torch which can be advantageously employed to start a fire in the furnaces of locomotive and other boilers.

Our invention consists mainly in providing a portable receptacle with a nozzle connected with the space near the bottom, through which nozzle the oil can be forced in a jet or spray, and With an inlet or inlets through which air under pressure or such air and the oil charge can be introduced into the receptacles. Preferably we provide independent inlets for the introduction of oil and air, and We provide, of course, avalve or valves for governing the inlet and outlet passages.

Our invention further consists in details of construction which Will be fully described in connection with the accompanying drawings, in which- Figure l shows the preferred form of our torch in position in front of a locomotivefurnace. Fig. 2 is an enlarged detail view of the inlet-openings and the oil-nozzle in our preferred form of torch, the section being taken at right angles to that shown in Fig. 3. Fig. 3 is a vertical section of the torch, taken at right angles to the Section of Fig. 2. Fig. 4 is a view on the line et 4.of Fig. 2,`the nozzle and air-pipe being removed; and Fig. 5 is a View similar to that shown in Fig. 4, the valve being shown in a dierent position.

A indicates a receptacle for oil and compressed air, which,while it may be const-ru cted of sheet metal, is preferably made of cast metal, as indicated in the drawings, so as to have asfewseamsand joints as possible. The substantially oval shape shown is a very convenient one, though the receptacle may be made in any desired shape.

B is a head orcover, in which We preferably form the inlet opening or openings for the oil and air and an outlet-opening for the oil.

The outlet-opening is connected with the bottom of the receptacle, so as to take its charge therefrom. AS shown,the outlet-opening b is connected by means of a passage b5 and a pipe D to the space near the bottom of the receptacle A.

The inlet-opening Z9 for oil is preferably connected to the Same passage b5 as is also the the air-inlet opening b2, the single valve C controlling all three openings. It will of course be obvious that the oil and air can be introduced into the receptacle through the same opening, and also that two or more valves can be employed to control the inflow' of oil and compressed air and the out-flow of the oil, but we much prefer the arrangement shown, Where one valve controls all the openings. This valve C is shown as a plug-valve operated by a handle c', andcis provided'with a port c', which is adapted, whenthe valve' is properly turned, to register with one of the openings b, b', or b2 and connect it throughV the chamber c2 and port c with the passage A passage c8 in the valve also controls the vent-port h3. This passage is so arranged that it will open the vent-port-when the port c registers with the oil-inlet opening b, as shown in Fig. 3.

Around the oil inlet b isconveniently formed a funnel B5, formed integral with the head B, through which funnel the oil may be poured.

The pipe D extends, as has been said, downy near the bottom of the receptacle. A Second pipe D extends into the receptacle or tank A and connects at its upper end with the ventport b3.

It will be noticed that When the valve C is in the position shown in Fig. l the air in the upper part of vthe tank can escape freely through the pipe D and the port b3 till the oil closes the bottom of the pipe D'. If any more oil is poured into the pipe D, vthe air in the upper part of the receptacle Will be somewhat compressed and will force the oil up the pipes D and D', and when oil appears at the vent-port b3 this will indicate to the operator that the tank is sufficiently filled. By using a shorter or longer pipe D a vgreater or less charge of oil can be given the torch, and We prefer to so proportion the parts that one charge of oil given the torch Will be sufficient to kindle one fire.

The nozzle F, through Which oil is forced from the receptacle, can of course be of any suitable form; but We prefer to employ a nozzle which gives a Whirl to the oil escaping from it.

The nozzle F is shown connected to a short pipe F', secured on the head B and opening from the passage b', a strainer f beingconveniently inserted in the pipe F', as shown.

It is also preferable, especially when the torch is employed in connection With locomotive-furnaces, to provide the air-inlet opening With a hose, as E, which is furnished With a coupler E', such as are employed to connect the various lengths of hose in an air-brake system, so that the air-inlet may be connected to the compressed-air reservoir of such a system, as indicated in dotted lines of Fig. l, and the reservoir given a charge of compressed air from this reservoir. It is, however, to be understood that the compressed air can be introduced into the torch in any Way. For instance, a hand air-pump may be employed either to give the receptacle a charge of compressed air before the torch is used to start a fire or to force out oil during its use. Also, While We prefer for the sake of convenience to arrange the parts as shown in Figs. 2 and 3 and to connect the nozzle to the space near the bottom of the receptacle by the pipe D, it Will be evident that the nozzle may itself be situated near the bottom of the tank, or that after being charged the tank can be turned upside down and the pipe D dispensed with. v

The torch is portable, and We provide it with handles A, as best shown in Fig. l, to aid in transporting it, and also when it is of the oval shape shown it is provided with feet a a, cast With the tank A. By securing the pipes D D to the cover B, as shown, they are conveniently removable With it. After the tank has been given its charge of oil and air, as described, the torch is placed in position in front of a furnace, as indicated at L', Fig. l, and the oil-outlet opened. The oil Will be forced out in a spray or jet by the pressure of the air, and When ignited Will quickly start the' fire. If a proper charge of oil has been given the torch, it may be left alone after it is in position and started, as it will continue operating till it has blown itself out.

Having noW described our invention, What We claim as new, and desire to secure by Letters Patent, isM

1. A portable oil-torch consisting of a suitable receptacle for oil and compressed air and having an outlet-nozzle for oil arranged so as to draw its supply from the bottom of the receptacle, independent inlets for oil and compressed air, and a single valve adapted to govern both inlet-openings and the passage leading to the outletnozzle.

2. A portable oil-torch consisting of a receptacle for oil and compressed air having an inlet-opening for oil and an outlet-nozzle, a valve for controlling these openings, a pipe D, extending to near the bottom of the receptacle and. connecting to the oil inlet and outlet openings, a second pipe D', connected to a vent-opening also controlled by the valve and projecting into the receptacle a less distance than the pipe D as described, whereby a definite charge of oil can be given the receptacle.

3. A portable torch consisting of a receptacle Afor oil and compressed air, a cover B therefor having inlet-openings for oil and air and an oil-outlet opening therein and a valve for controlling these openings, and pipes D and D secured to the cover Bso as to be removable therewith.

4. A portable oil-torch consisting of a receptacle A for oil and compressed air, a cover or head B therefor having an oil-inlet opening provided with a funnel B2 an inlet for air and an oil-outlet and pipes D and D secured to the head B and extending doWn into the receptacles for different distances as described.
